Embodiment Construction

[0026] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0027] Such as Figure 1 ~ Figure 3 As shown, the shield tunnel segment information visualization modeling method of the present invention includes the following steps:

[0028] S1. According to the lining ring parameters and tunnel design axis information, establish a segment ring 1 on the graphics platform; the segment ring 1 includes a standard ring (S), a left-turn ring (L), a right-turn ring (R) and a general Segment ring. The segment ring 1 is assembled by bolts. After creating the segment ring, add the non-geometric information of the segment ring. The non-geometric information includes segment ring number, mileage, design unit, construction unit, concrete...

Abstract

The invention discloses a shield tunnel segment information visualization modeling method. The method comprises the steps of S1, establishing a segment ring in a graphic platform according to lining ring parameters and tunnel design axis information; S2, calculating the assembly point position and segment type of each circle of segment according to the horizontal curve element and vertical curve element of a shield tunnel circuit with the minimum value of deviation between a tunnel center line and a circuit center line as standard; S3, placing the segment ring element established in S1 at a corresponding assembly point position according to the shield tunnel segment assembly point and segment type data. Through assembly of the whole segment ring, segment positioning is simplified, background action procedures are simplified, positioning precision is improved, a modeled segment and an actual segment are assembled in the same way, the condition of a tunnel can be checked any time conveniently in the later stage, and modeling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of shield tunnel segment modeling, and in particular relates to a shield tunnel segment information visualization modeling method. Background technique [0002] In recent years, shield method construction has occupied a dominant position in tunnel construction and has become the main form of urban tunnel construction. Segment assembly is an important technology in shield tunneling construction. At present, there are mainly two methods for layout and assembly of shield segments in engineering: two-dimensional and three-dimensional. Among them, the two-dimensional segment typesetting is only carried out according to the width of the segment on the longitudinal section, and the spatial position of the segment is determined according to the mileage and elevation of the segment; while the current three-dimensional segment typesetting is for general-purpose segments, according to The geological survey uses a cub...
